maildir not created

I did "perfect installation for ubunto 6.06" or something like this, on AMD64 machine.
now I can send mail (with TLS) virutal users (created via ISPconfig) can get mail, but local computer users don't.
when trying to get mail through telnet I get error on maildir not existing.
though maildir is enabled in ISPConfig no mail dir was created for local user.
I tryed copying a maildir folder from virtual user, no I can perform telnet to 100, but no mails resieved...
here is main.cf:
